I been running my asterisk server for a few months, however there are times when we receive incoming calls from the PSTN with no one on the otherside.
There are also times where extensions will ring with no person being on the other side.
I do not have any cron jobs running.
I tested the incoming PSTN lines numerous times from an outside lines and in every case of testing the call was successful with 2 way audio.
Anyone has any ideas on what would be the possible problem of these GHOST calls
